HAPPY? ANNIVERSARY

So, today is my wedding anniversary.. 3 years ago on this very day, I was the happiest (and most beautiful :) ) lady and bride. It wasn't just the thought that I was getting married to the man I loved, my life was also generally good and I was just a happy person. Getting married brought changes, biggest of which was I had to move to an entirely new country. Get out of my comfort zone, leave my friends, leave behind the city I loved and knew to a new place that was at times a strange place.
3 years on, what wise words do I have... none. I'm probably more confused than I was before I got married. It's funny, pre-marriage, I would attend bridal showers and give 'advice' (what does an unmarried girl know about marriage..fun times though) and now,the only thins I say is 'All best' to the person about to make the leap.
I was once told that your husband/ wife is someone you 'do life with' - you make investments together, you have babies, you raise your kids, you pay bills and hopefully you progress and somehow support each others goals. At the time, I thought that was a rather sad way to think of your spouse, but now I wonder...was there some wisdom in that.. maybe it is true..maybe the way to have successful and long lasting marriage is to stop thinking of your spouse as this person who is going to be your best friend and someone you will spend long cold nights with, cuddling in front of the fireplace. Your spouse may be too busy getting on with life, working long hours to make sure bills are paid, savings are maintained and personal goals as well are attained. When that happens, I find it hard to engage in usual, un thought out coversation. He is too busy with work and in turn I have also started my own small side hustle (which has started off well!) to keep me busy and keep the loneliness at bay.
What is the future for us? I wonder...I really do.
I feel that soo many days of silence are passing that we may soon not know how to talk to each other. Tears are in my eyes now, because sadly I feel we are becoming strangers to each other.
Marriage can be and should be a wonderful and enriching experience... sadly, right now, mine isn't.
